We have done a number of conference rooms and pretty much run HDMI, VGA and composite as well as analog audio. It covers everything most people need. We also leave a number of adapters like DVI>HDMI, headphone jack to RCA, etc and educate the staff. A good control system is also critical so it is super easy for them to control everything. We also put instructions on the screens for connections.

I've been using switches from Kramer or Extron. Unfortunately I'm on the road and don't have the model numbers off the top of my head.

After thinking it over a little, I think it might be simpler to have only hdmi ports on the conference table pop ups and provide the following adapters:

1. VGA and l/r audio to hdmi converter
2. Display Port to hdmi converter
3. DVI and l/r audio to hdmi converter

that should cover 98% of needs.

Atlona makes an auto sense 3x1 hdmi switch I could install under the table that would switch whichever hdmi port is being used on to the matrix. Another installer told me that that he has used that Atlona auto sense switch dozens of times and they work well.

Make the cable easy to change and leave spares.

I have not read all post's but, here is a very simple solution to sending a video signal to your matrix without using wires.

If your client want's to send more content than data, this is a great solution.

If you are sending video content from your PC, you will be ristricted to 20FPS

The unit does not car if you use PC or mac or iPad.

For PC and MAC, just plug the plug the USB button and just press it once you are ready to send your content.

The base unit, that uses it's own provided wi-fi signal to connect to it's transmitters, can output via DVI-D and display port.

I've tested it and, I was able to use a display port to HDMI and a DVI to HDMI adapter on each output and it all worked well.

You will be able to send 4 computer image at the same time to your screen if needed.

Soon, Barco will release a new firmware upgrade that will allow you to :
1 - allow audio to be transmitted
2- iPad connection (you will need to add a AppleTV unit and clickshare link)
3- Dual screen
4- Windows 8 compatible

Have a look at their site and here is a link to the PDF file too

We use at least one Crestron DM-TX-201C with an Altinex TNP-128. This gives you both VGA and HDMI. It also gives you 3.5mm stereo.
